Definitions
- liquid crystal mixtures are required, which are very have a wide working temperature range, on the other hand the smallest possible Have threshold voltage, for example for use in automobiles which can easily reach a temperature range from -40 ° C to 100 ° C, but also for portable devices such as mobile phones and notebook PCs ..
- the object of the present invention is therefore to provide new components for the Use in nematic or cholesteric liquid crystal mixtures to provide the positive values of dielectric anisotropy combined with a favorable ratio of viscosity and clearing point feature.
- the compounds are said to be highly light and UV stable as well as being thermally stable.
- they should be suitable for high, voltage holding ratio (VHR) '. They should also be easily accessible synthetically and therefore potentially be inexpensive.
- the compounds of formula (I) are in, preferably nematic or cholesteric, liquid crystal mixtures used.
- the invention Liquid crystal mixtures contain at least one compound of the formula (I), preferably in an amount of 1 to 40 wt .-%, based on the Liquid crystal mixture. They preferably contain at least 3 more Components.
- the invention also relates to a liquid crystal display, this Contains liquid crystal mixtures.
- the person skilled in the art can introduce the substituents R 2 in the form of an alkyl group using standard methods of ortho-metalation — for example using “locksmith base”; alternatively, the primarily formed lithium compound with boric acid esters can be converted into the corresponding boronic acid and this in turn can be converted into the corresponding 2-hydroxyphenanthrene derivative by oxidation.

Description
- R1
- H, einen Alkylrest mit 1 bis 12 C-Atomen oder einen Alkenylrest mit 2 bis 8 C-Atomen, worin auch jeweils eine (nicht terminale) -CH2-Gruppe durch -O- oder -C(=O)O- ersetzt sein kann und/oder ein oder mehrere H durch F ersetzt sein können,
- R2
- H, F, einen Alkylrest oder Alkyloxyrest mit 1 bis 12 C-Atomen oder einen Alkenylrest oder Alkenyloxyrest mit 2 bis 8 C-Atomen, worin auch jeweils eine (nicht terminale) -CH2-Gruppe durch -O- oder -C(=O)O-ersetzt sein kann und/oder ein oder mehrere H durch F ersetzt sein können,
- M1
- -C(=O)O-, -OC(=O)-, -CH2O-, -OCH2-, -C=C-, -CH2CH2 oder eine Einfachbindung,
- m, n
- unabhängig voneinander Null oder 1; m+n 0 oder 1,
- p, q
- unabhängig voneinander Null oder 1; p+q 1 oder 2,
So kann beispielsweise Ersatz von 2-(2,3,4-Trifluorphenyl)ethylbromid (hergestellt analog R.P.Houghton, M.Voyle, R.Price, J.Chem.Soc. Perkin Trans 1 (1984), 925) durch 2-(2,3-Difluorphenyl)ethylbromid [126163-29-9] zu Verbindungen der Formel (Id) bzwz. (Ih) führen, in denen R2 F bedeutet; gleichermaßen können durch Einsatz von 2-(2-Fluorphenyl)ethylbromid [91319-54-9] als (II) Verbindungen der Formeln (Id) bzw. (Ih) erhalten werden, in denen R2 = H ist. Hierauf lassen sich die weiter unten aufgeführten Folgereaktionen einer ortho-Metallierung anwenden.
Für die Synthese des Zwischenproduktes (X) stehen mit T.Cuvigny, H.Normant, Organometallics Chem.Synth., 1(1971) 237 bzw. T.Takeda, H.Taguchi, T.Fujiwara, Tetrahedron Lett. 41 (2000) 65 Verfahrensvarianten zur Verfügung.
Ausgehend von (V) kann der Fachmann nach Standardmethoden der ortho-Metallierung - z.B. mit "Schlosser-Base" - den Substituenten R2 in Form einer Alkylgruppe einführen; alternativ kann die primär gebildete Lithiumverbindung mit Borsäureestern in die entsprechende Boronsäure und diese wiederum durch Oxidation in das entsprechende 2-Hydroxy-phenanthrenderivat überführt werden. Letzteres kann durch Williamson-Ethersynthese zu Verbindungen der Formel (Ii) [bzw. analog (Ig)] transformiert werden, in denen R2 eine Alkyloxygruppe ist; durch Veresterung können Verbindungen der Formel (I) erhalten werden, in denen M1 -OC(=O)- bedeutet.
